Horde authentication failure


I updated my server yesterday and this morning I couldn’t login to horde. I think this has happened 2 times in the past. I tried to figure out what was going wrong, but I’m not sure exactly how to troubleshoot horde logins. I end up uninstalling the horde app and reinstalling it. That fixed the issue.

Has anyone else seen this behavior or can point me to how horde is handling it’s authentication so I can try and troubleshoot this when it happens again? TIA
